IMPROVEMENT INl APPARATUS FOR MAKING EXTRACTS FROM VEGETABLE AND ANIMAL SU BSTANCES.

The Schedule referred to in these Letters Patent and making part o the same.

To all whom it may conce/rn.-

Be it known that I, LOUIS BRAUEILYO' the city and county of Philadelphia and State of Pennsylvania, have made a new and useful Improvement in Apparatus for Making Extracts, Decoctions, Tinetures, and the like, from Vegetable and AnimalSubstances; and I hereby declare the following to hea full and exact description of the same, reference being had to the accompanying drawing.

Heat is a necessary agent in obtaining solutions and extracts from vegetable and animal substances.

rJlhe liquid used should be kept as near as possible to the boiling point without actual boiling, so as to drive off the aroma or more volatile portions of the extract.

The object of my invention is to construct simple' and convenient apparatus on this principle.

In former patents issued to me, dated December 1, 1868, and. March 15, 1870. I have described such My present invention consists in certain modifications whereby the object is accomplished with greater certainty and simplicity.

In the drawing-4 Figure 1 shows the general construction of my tpparatus.

Figure 2 shows other forms or modiications, a., b, c, d, e, f, g, and h, so as to adapt the apparatus to various uses.

The apparatus is composed of a vessel or boiler, A, and extractor, B, and a cover, C. v

The boiler A may be' of any form or size desired. It must, however, be large enough to contain the vessel B, and also sufficient water to furnish steam to heat the vessel B during the length of time required to produce the extract. This will, of course, vary In fig. 1 the extraction-vessel B is attached to and forms the cover of vessel A--tliat-is, to the upper side ot' vessel B is xed a flange, in, turned down as shown at n, so that when vessel B is placed in the position shown in the drawing it closes the top of vessel'A.

A handle,\p,l is attached to flange m, so as to lift vessel B off from vessel A.

The vessel B is provided with cover C, provided with knob e and flange t.

In forms c and c the cover of vessel B is held on In forms b and d vessel B is placed entirely inside of vessel A, which is provided with hasp and stopple, so, as to be locked. l

In i'orms e and f the vessel B is made to projectconsiderably above vessel A.

In form g vessel B is made large enough tofit into and ll the mouth of vessel A.

In forms a and c the bottom of vessel B is provided with a projecting perforated tube, to serve as Va han-- dle to turn vessel B while emptying its contents.

It will be readily seen that other similar modifications may be made, each, however, embracing the essential parts shown in iig. 1.

The method of using my invention is as follows:

Vessel A ischarged with suicieut water to boil during the time required to make the extract.

The material from which the extract is to be made. is placed in vessel B, together with the proper liquid to i'crm the. extract.

Vessel B is then closed and placed iu vessel A so as to close it, and heat applied so as to boil the water in vessel A.

Neither the water nor the steam in vessel .A comesV in contact with the contents of vessel B.

It is not important, generally, to be particular as to the exact length of time. that vessel-B is subjectedV to the'heat in vessel A. In fact, one of the. important advantages of my invention is that vessel B may be let't'in vessel A an indifferent length of time without dissipating or expelling the aroma or essences that may be dissolved in vessel B.

This makes makes my apparatus of especial use for families, apothecares, chemists, dyers. restaurantkeepers, and many others.

'l he vessel A may be arranged so as to be heated over a stove, open tire, gas-burner, or suitablelamp.v

My invention is applicable to tea and coiee-pots of any of the ordinary forms; alsoto vessels such as are used now for making beef-tea, jellies, extracts of roots, herbs, and other substances.-

For apothecaries and others, in making tincturcs, this apparatus will have great advantages.

. Clhe contents of vessel B may be treated with the proper solvent as oftenas required.

When used in making tea or coffee, after the extract is formed in vessel B, it may be poured oli" into vessel A, with the proper amount of water.

My apparatus will befound exceedingly conven-` ient in the sick-room, as by it all the food and drink required by .the sick person may be kept ready prepared inthe niost'palatable form, and without danger of spoiling either bybecoming overcooked or cold.

Wine, spices, and any suitable ilavoring material may be placed in vessel B with the proper solvent and the material from which the extract is to be made.

I do not claim the application of a water or steaml vessel B-vvill be condensed and collected. This vessel is suitable for cooking puddings and other articles.

Having thus described my invention,

What I claim, and desire to secure' by Letters Iatent ot' the United States, is-

l. The combination and .arrangement of a boiler and an extractor so as to operate substantially as herein set forth.

2. The vessel A, in combination with the removable vessel B, as and for the purposes set forth.
